applied to the input arguments before the series is evaluated. The
map depends on the <code class="docutils literal notranslate"><span class="pre">domain</span></code> and <code class="docutils literal notranslate"><span class="pre">window</span></code>; if the current

used by themselves outside this class, then the linear function
must be substituted for the <code class="docutils literal notranslate"><span class="pre">x</span></code> in the standard representation of
the base polynomials.</p>
